JOHN GOGERTY, OF DECATUR, ILLINOIS.

SCOT-CONSUMER AN D SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 331.785, dated December 8, 1885.

Application filed February 11, 1885.

To aZZ whom/it TIL-(by concern Be it known that I, JOHN GOGERTY, a resident of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Combined Spark Arresters and Smoke Consumers, of which the following is a specification.

The object of my invention is to produce a combined soot-consumer and spark-arrester that will be suiiiciently cheap and simple to be of practical use in ordinary stove-pipes, and which may be placed in position in the pipe without the use of rivets or other secur- My invention consists in a conical tubular metallic sheet, perforated at suitable intervals throughout its upper portion, provided on its upper extremity with a heat-retarding plate, and provided at its lower extremity with an imperforate band adapted by size and conformation to precisely intervene between two joints of pipe, or between ajoint of pipe and the rim on the pipe-opening of a heating apparatus.

The danger and annoyance that my device is designed to overcome will be readily apparent, as the sparks cannot escape to enkindie a fire, nor the soot accumulate in the smoke conveyor or become distributed on roofs, due, to be washed into cisterns, or beways.

In the drawings accompanying and forming a part of this specification, Figure l is a perspective view of my device, and Fig. 2 is a view of a joint of pipe partiallybroken to show my device in position therein.

1) represents a solid portion of the pipe, and a the perforated portion of the same. a is a cap that completely closes the upper end of the pipe, and to a certain extent acts as a damper. (Z is thejoint of ordinary stove-pipe, in which my device is represented in Fig. 2.

The dotted lines in Fig. 1 indicate the position of the smoke-conveyer, and the dotted lines in Fig. 2 indicate the posit-ion of my de vice in pipe d.

The pipe at b may be more or less tapered, and the perforations may be larger or smaller, according as the draft is strong or weak, and

Serial No. 155,575. (X0 model.)

the soot-producing capacity of the fuel used less or greater.

Where wood is used as a fuel the taper of the pipe need not be great, and the perforations may be formed of small size. When, on the other hand, bituminous coal is used, the

taper should be greater, and the perforations of a size to correspond with the strength of the draft.

In operation the sparks are arrested by contact with the converging sides of the pipe or with the cap at the termination of the same, while the soot accumulates around the perforations and on the sides of the pipe until it becomes ignited and consumed by means of sparks or heat from the stove or other heating device with which it is connected. The plate 0 hastens the combustion of the soot by retarding the heat from passing up the pipe.

The spark-arrester is formed of correct size and shape to fit over ajoint of the conveyingpipe, (or over the pipe-opening of the heating apparatus with which it is intended to operate,) and the connection is completed by passing another joint of the conveying-pipe over the plane surface of the sparkarrester, as shown in Fig. 2.

XVhile specially designed for the purpose above set forth, my device is nevertheless adapted to operate as afilter or screen for various substances, under various circumstances, many of which will readily suggest themselves.

Having thus described my invention, I claim as new and desire tosecu re by Letters Patent The combination of a conical tubular sootcollector, perforated at suitable intervals throughout its upper portion, a heat-retarding plate on the upper extremity of the perforated soot-collector, and an imperforate band on the lower portion of the soot-collector, of

suitable size and conformation to precisely intervene between pipe-joints, as set forth.

In testimony whereof I sign my name in the presence of two subscribing witnesses.

J OHX GOGERTY.
